Improvements in Hinge Mechanisms for V \vmdows, &c'.,

of whielrthe following is aspeolficatlon.

This invention relates to lmpro 'ement-s in hinge mechanisms, and it has for its 013-.

j ect to provide a construction which may 'be very cheaply and accurately manufactured, and which is so constructed that it may be applied to a window after the latter has in other respects been completely finished, and may also with equal facility be detached. The invention will be. readily understood from the following description, reference being had to the accompanying drawings, in Which Figure 1 is a fragmentary View showing in elevation parts of a window frame and sash equipped with my invention; Fig. 2 is a sectional view taken on line 22 of 1; the sash being show'nin partly open or tilted position 5 Fig. 3 is a. face viewof the stationary member ofthe hinge, the pintle or pivot stud being shown in section; Fig. 4 is a View showing a fragmentary portion of the window frame and the manner of ad just-ing the stationary member .to position in the frame; Fig. 5 is a view showing the stationary hinge member in central vertical section and the movable member in {elevation, the two members being shown in properly assembled relation; Fig. 6 is a View taken on-iine 66'-of.Fig. 5 showing the manner in which the movable member is applied to the window sash.

In mounting window sash within the frames, particularly where the structure is of the fireproof type and the sash is designed to close automatleally, it 18 import ant to provide a construct-ion in the pivot or hinge connections which permits of such'adjustment as to allow the sash to swing with the utmost freedom, i.- e. without binding in any of its movements, and also so constructed that the axis of the hinge falls consideralfly outside of that center of gravity which comcides with the plane of the window in order that the weight-of the sash itself may serve "to effectually close it when released. Metal windows of the fireprooftype-are usually,

and sash have been completed and beforc'f the glazing is set. 1 It requires much carcand the expenditure of unnecessary time to aint ly around the hardware attacliments",.

carefu and on the other hand it"produces an un sightly finish to undertake to paint or otherwise coatthe hardware attachments besides tending to clog the hinges and interfere with the freedom of movement of the sash, These and other oluections l overcome-n 1 p my present (-OllStlUtt'lOl'l.

Describing the mechanism,- l tlslgnat stationary member which takes the form of.

astrap of metal ha ing end portions? and 3 adapted to restllatwise against. the wnnlow frame, and an intermediate -or central por-j tron wl-nch 1S oilset and hes in a plane near-:"

the edge of the window sash. The base-pun tions 2 and 3 are )referahly longitudinally slotted, as indicator at 5, and the ITIOIIIlJLP-ls secured to the side frame 6 of the window by means of screw-bolts these slots. ing is arranged a flat strap or plate 8 aperturcd and threaded to receive the in'ner'ends of the screws 7, as seen clearly in Fig. 5. In

order that thisrein-forcing clamping "plate may bC-iltlJLlStCd to posltlon-jal'tei" the w1'ndow' frame is constructed, the frame is slotted,- as indicated at 9, the slot being somewhat wider "than the thickness of the plate 8, and at pointsin lateral registcrwitli the screws 7 the slot 9 is laterally enlarged or notched, as indicated at 10. The screws 7 areof considerable length; and'hy applyingthe plate 8 to the ends thereof, substantiallyas shown in Fig, 4,;1 nd presenting the edge ofthe plateto the slot it may be passed through the casing and into position, or buttoned in, so to'speak, andthereafter b'rong'lit into the proper plane and position, and the screws. tightenec down so as tocl'a'xnp-the sheet metal of the frame firmly between the )late 8 and the baseportions'of the mem-.

inserted throughlnsidc oltthe sheet metal cas-' to present a mere Iiished appearance and to forma sn'iodii bear g for the p By using'th'e eyelet 13 these hingemembers 4 may be blanked out-with an ordinary punch "press, the holes produced by which are more or less rough. t p 144 designates as a whole the companion hinge member, which is mounted upon the sash, and will therefore for. convenience of description be termed the movable member. This member has its end portions and 16 constructed substantially like the correwith a base portion adapted to be fixedly se- 55 cured against a frame and-an intermediate -1- oflset web portion provided with a pintle' socket, a strap-likepintle member provided at each end with a base portion adapted to be secured to a frame and an intermediate ofiset v'eb aortion formed into an elongated transverse y extending socket-like eye, and" ar- I the" intle or pivot stud 12.

-sponding portions 2' and 3 of the member already described, and it is secured to the side rail of the sash in substantially the same,

1manner, viz: by screws 7 extending through a slot 9 in the sash rail and into a clamping plate 8 adjusted toposition as before de scribed. The central portion of the member" 15 isdeflected laterally outward and formed into an eye 17 within which is rigidly seated The pintle is .hea ed at one end, as-indicated at 18, and

through its opposite end inside of the offset ortion 4 of the member 1 a s lit key 19 isinserted. The member 15 is s otted at the byreason of the width of the slot 9 at the points where screws 7 pass therethrough so that it may be adjusted up and down, and

, points where these screws pass through the samethe member 15 may be adjusted later all i also.

11 windows of this character it is desirable to limit the extent to which the 'sashmay open on its pivotal axis, and to this end the members 1 and 15 are each rovided at their lower end with eyes 20 wit which are connected the respective ends of a short chain 21 While 'I have shown and described a pre- I ferredembodiment of the invention, yet it will be understood that the details ma be somewhat modified without departing om screw-bolts inserted through the base 2. Ahinge mechanism com rising a straplike socket member provide ateach end ranged at right angles to-said first web por t1on,,and a pintle fixed in said eye and .en aging the socket of the first mentioned mem er. 3. A hinge mechanism comprising'a straplike socket member having at each end a base I portion and a screw-bolt inserted there- 'through, an intermediate ofiset portion pro-- 7O vided with a pintle socket, a reinforcing clamping plate mounted upon the inner ends of said screws, a strap-ii:

e pintle member having at each end a base portion, and a screw-bolt inserted therethrough, an offset intermediate' portion for'medlin'to an elongated socket-hke eye and arranged at right fixed in said socket of the rst mentioned member, and a clamping plate mounted upon the inner ends of the screw-bolts andextending through the base ortionthereof.

4. n' combination with a hollow metal window frame-provided with a narrow slot in one of its faces and a hollow metal sash frame fittingthe window frame and likewise pro vided with aslot in one of its faces, a hinge angles to' said first'ofiset portion, a pintle sye and adapted to engage the mechanism comprising a strap-like socket member having base portions a through said base portions. and said'slot, a

apted to rest flatwise against the face of the window frame over the slot therein, screw-bolts inserted reinforcing clam ingplate threaded u on the inner ends of sai screw-bolts'anduri erl'ying the slot, a stra -like pintle -member having base portions a apted to rest flatwise against the sash frame and over the slot therein,

POI-

tions and-saidslot, a clamping plate threaded upon the-inner ends of said latter screw-bolts and underlying said slot, and a pintle carried by said pintle member and operativelyen gaging a socket in the socket member. THOMAS l. DUFFY. v
